[0001] This is a Continuation-In-Part of Application No. 08/394,234.

BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The present invention relates generally to a satellitebroadcasting receiving and distribution system and more particularly toa broadcasting receiving and distribution system that will allow for thetransmission of vertical and horizontal or left-hand circular andright-hand circular polarization signals to be transmittedsimultaneously via a single coaxial cable.

[0004] 2. Description of the Prior Art

[0005] Satellite broadcasting has become very popular throughout theUnited States. Conventionally, broadcast signals are transmitted throughan artificial satellite at very high frequencies. These frequencies aregenerally amplified and are processed by a particular device afterreceived by an antenna or antennas and prior to application to aconventional home television set or the like.

[0006] Typically, broadcasting systems comprises an outdoor unitgenerally associated with the antenna and an indoor unit generallyassociated with the television set or the like. Both units, indoor andoutdoor, are coupled via a coaxial cable.

[0007] A problem associated with these types of systems is that they aredesigned to accept signals through a line of sight. Accordingly, if thesatellite is not visual from a building, then the signal cannot betransmitted. Thus, these systems are rendered useless for high-rises,hospitals, schools, and the like. These systems are limited in usage,and as such, can only be utilized in residential homes.

[0008] As an example, U.S. Pat. No. 5,301,352 issued to Nakagawa et al.discloses a satellite broadcast receiving system. The system of Nakagawaet al. includes a plurality of antennas which, respectively, include aplurality of output terminals. A change-over divider is connected to theplurality of antennas and includes a plurality of output terminals. Aplurality of receivers are attached to the change-over divider forselecting one of the antennas. Though this system does achieve one ofits objects by providing for a simplified satellite system, it does,however, suffer a major short-comings by not providing a means ofreceiving satellite broadcasting for individuals who are not in thedirect line of sight to the antennas. This system is silent to the meansof simultaneously transmitting vertical and horizontal polarized signalsvia a single coaxial cable.

[0009] U.S. Pat. No. 5,206,954, issued to Inoue et al. and U.S. Pat. No.4,509,198 issued to Nagatomi both disclose yet another satellite systemthat includes an outdoor unit that is connected to a channel selector.In this embodiment, the satellite signal receiving apparatus receivesvertically and horizontally polarized radiation signals at the side of areceiving antenna. The signals are then transmitted, selectively, toprovide for either one of the vertically or horizontally polarizedsignals to be transferred. Hence, utilizing a switch, only one polarityis transmitted. This design and configuration provides for one coaxialcable to be utilized, but does not provide for the vertical andhorizontal signals to be transmitted simultaneously, but rather,selectively.

[0010] Systems have been attempted for transferring two frequencies onthe same co-axial cable. Frequencies of the same polarity can easily betransmitted via a single co-axial cable, however, transmitting twosignals, from two sources, each of different polarities can be achallenge. In some satellite configuration systems, once a timingdiagram is plotted for the signals transmitted, it is seen that aforbidden path occurs between frequencies of 950 MHz and 1070 MHz.Inherently prohibiting the frequencies within that range to betransmitted successfully. Hence, it is desirable to obtain a systemwhich will not allow for conversion to occur at frequencies of theforbidden conversion.

[0011] As seen in German Patent Number DE4126774-A1, signals can betransmitted within the range of the forbidden path, thereby, providingfor a non-working system. Additionally, this product, like the assemblydisclosed in Japanese Application No. 63-293399 both disclose a systemwhich receives a single signal and demultiplexed them into vertical andhorizontal polarized signals. These systems, are complex and require anumerous amount of components in order to employ the invention. Thisincrease in components will inherently cause an increase in componentfailure. Further, these systems fail to disclose a means of reconvertingthe signals into their original frequency and polarity, a necessity forsatellite systems. Consequently, providing a signal which will notmaintain its respective polarity.

[0012] Accordingly, it is seen that none of these previous effortsprovide the benefits intended with the present invention, such asproviding a broadcasting receiving and distribution system that willallow for the transmission of vertical and horizontal or left-handcircular and right-hand circular polarization signals to be transmittedsuccessfully and simultaneously via a single coaxial cable.Additionally, prior techniques do not suggest the present inventivecombination of component elements as disclosed and claimed herein. Thepresent invention achieves its intended purposes, objectives andadvantages over the prior art device through a new, useful and unobviouscombination of component elements, which is simple to use, with theutilization of a minimum number of functioning parts, at a reasonablecost to manufacture, assemble, test and by employing only readilyavailable material.

SUMMARY OF THE INVENTION

[0013] The present invention provides a satellite broadcast receivingand distribution system that will permit for the transmission ofvertical and horizontal or left-hand circular and right-hand circularpolarization signals simultaneously via a single coaxial cable. Thesystem of the present invention will accommodate two different polaritycommands from two or more different sources at the same time. Thissatellite broadcast receiving and distribution system of the presentinvention will provide for the signals received from the satellite to beconverted to standard frequencies so as to permit for signals to travelvia existing wiring which the present day amplifiers can transport inbuildings, high-rises, hospitals, and the like so that satellitebroadcasting can be viewed by numerous individuals by way of a singlesatellite antenna.

[0014] The satellite broadcast system of the present invention comprisesa satellite antenna which receives the polarized signals, a head-infrequency processor for converting the polarized signals, a singleco-axial cable for transmitting the converted signal, a head-outreceiver processor for reconverting the signals to their originalfrequency and polarity, and a source, which receives the signals intheir respective original frequency and polarity. Structurally, thehead-in frequency processor is coupled to the head-out receiverprocessor via the single co-axial cable. The source is coupled to thehead-out receiver processor.

[0015] Hence, to allow for successful conversion, the head-in processorconvert the received signals of two different polarities to frequencieswhich permit for transmission simultaneously. The head-in processor willalso accommodate two different polarity commands from two or moredifferent sources at the same time via the single cable.

[0016] The single cable couples the head-in processor to the head-outprocessor. Once in the head-out processor, the signals are re-convertedto their original state for transmission to the source (i.e.television).

[0017] Accordingly, it is the object of the present invention to providefor a satellite broadcast receiving and distribution system which willovercome the deficiencies, shortcomings, and drawbacks of priorsatellite broadcast systems and signal and polarity transfer methods.

[0018] It is another object of the present invention to provide for asatellite broadcast receiving and distribution system that will convertdifferent frequencies and different polarized signals in order to permitthe signal to be transmitted via a single coaxial cable.

[0019] Another object of the present invention is to provide for asatellite broadcast receiving and distribution system that will provideservice to mid/high-rise office buildings, condominiums, schools,hospitals and the like via a single satellite.

[0020] Still another object of the present invention, to be specificallyenumerated herein, is to provide a satellite broadcast receiving anddistribution system in accordance with the preceding objects and whichwill conform to conventional forms of manufacture, be of simpleconstruction and easy to use so as to provide a system that would beeconomically feasible, long lasting and relatively trouble free inoperation.

[0021] Although there have been many inventions related to satellitebroadcast receiving and distribution systems, none of the inventionshave become sufficiently compact, low cost, and reliable enough tobecome commonly used. The present invention meets the requirements ofthe simplified design, compact size, low initial cost, low operatingcost, ease of installation and maintainability, and minimal amount oftraining to successfully employ the invention.

[0022] The foregoing has outlined some of the more pertinent objects ofthe invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0030] As illustrated in FIG. 1, the satellite system 10 of the presentinvention includes a receiving satellite 12 that will transmit signals(Vertical-polarized signals and Horizontal-polarized signals orleft-hand circular and right-hand circular polarization signals) to ahead-in equipment frequency processor 14. It is at this head-inequipment frequency processor 14 where the signals are receivedsimultaneously and then transmitted via a single coaxial cable 16 to thehead-out receiver processor 18. This will enable for the single coaxialcable 16 to transmit signals of two different polarities and frequenciessimultaneously. From the head-out frequency processor the signals arereconverted to its original state and then transmitted to a source 20.As seen in FIG. 1, the two different polarities (Vertical-polarizedsignals and Horizontal-polarized signals or left-hand circular andright-hand circular polarization signals) are transported to the sourcevia separate cables 22 a and 22 b, respectively.

[0031] The system of the present invention includes separateembodiments, and the first embodiment is illustrated in FIG. 2. As seenin the first embodiment of the present invention 10 a, there is shown ahead-in frequency processor 14 a couple to either a first head-outfrequency processor 18 a or a second head-out frequency processor 18 b.

[0032] It is noted that FIG. 2 illustrated the head-in processor 14 a tobe coupled to two separate head-out processors 18 a and 18 b,respectively. This is shown for illustrative purposes only. Inactuality, only one head-out receiver processor is utilized with thehead-in processor 14 a. The type and embodiment used for the head-outreceiver processor is dependent to the combination of the satellitereceiver and source that is utilized.

[0033] As seen in FIG. 2, the head-in equipment frequency processor 14 awill receive two signals or two separate polarities and converted themto separate frequencies for enabling transmission via a single coaxialcable 16 b.

[0034] A low-noise block converter (LNB) 24 will receive the signalsfrom the satellite 12. This LNB 24 is conventional and is used foramplifying the respective polarized signals (Vertical-polarized signalsand Horizontal-polarized signals or left-hand circular and right-handcircular polarization signals). Accordingly, after signals are received,they pass the low-noise block converter 24, to provide for the signalsto enter the head-in equipment frequency processor 14 a (illustrated inFIG. 2 as dashed lines) via conduits 26 a and 26 b, respectively.

[0035] The head-in equipment frequency processor 14 a, illustrated inFIG. 2, provides for the signals to be converted, via converters 28 and30, to the frequencies which the present day amplifiers can transport.In this stage of the system, the object is to convert the signals of onepolarity up (via converter 30) and to convert the signals of secondpolarization down (via converter 28). This will render the convertedsignals to be transmitted without emerging into the forbidden frequencyconversion.

[0036] From the conduits 26 a and 26 b, the signals are transmitted to afirst converter or down converter 28 and a second converter or upconverter 30. These frequency converters, 28 and 30, respectively,convert the entered frequencies to a frequency which present dayamplifies can transport. The converters will be discussed in furtherdetail in FIGS. 3a and 3 b. The utilization of two converters permit forthe acceptance of two signals or polarized transponders that are of adifferent frequency.

[0037] In the down converting means 28, the transponder is converteddown to a specified frequency. The specified frequency is the frequencythat is required for the present day amplifiers for transportation. Thenewly converted frequencies are amplified through the amplifying means32 a. At means 32, the converted frequencies are amplified so not tocreate second harmonics. These signals are then transferred to aconventional four way splitter 34 a.

[0038] In the up converting means 30, the transponders are converted upto a specified frequency. The converted frequencies then are converteddown via a down converter 36. This process of converting up and thendown provides for frequencies to be converted without difficulties andavoiding the forbidden conversion area.

[0039] The converted signals are transferred to the four way splitter 34a in order to combine the frequency of the amplified signal of 32 a andfrequency from converter 36. To synchronized the system, the frequenciesfrom the phase lock loop (PLL) transmitter 38 a are transmitted to thesplitter 34 a.

[0040] From the splitter 34 a, the signals are passed through an ACpower separator 40 which routes 60 Volts power to a DC power supply of18 Volts. This will permit for the dual frequencies from the satellitedish 12 to be transmitted simultaneously via a single coaxial cable 16b. Dependent upon the length of the cable, an optional conventionalamplifier 42 can be coupled thereto. Power from a power source 44 isinserted into the lines via a power inserter 46. The signals areamplified, as need, with additional amplifiers 48. It is noted that theamplifiers are optional and are dependent to the distance that thehead-in frequency processor 14 a is located from the head-out frequencyprocessor 18 a or 18 b. The power supply and power source 11 energizethe head-in frequency processor 14 a.

[0041] From the single coaxial cable 16 b, the signals are adjusted viaa tap 50 a to permit for the appropriate decibels that are required forthe head-out processor 18 a or 18 b.

[0042] The head-out frequency processor used for the head-in processor14 a illustrated in FIG. 1, can include two embodiments, dependent uponthe embodiment for the source in combination with the satellitereceiver.

[0043] The first embodiment for the head-out frequency processor isillustrated in FIG. 2 by way of dash line 18 a. As seen in thisembodiment, the simultaneously transmitted signals enter the processorvia conduit 16 b. The conduit 16 b is coupled to a conventional four (4)way splitter 34 b. A conventional phase lock loop (PLL) receiver 56 a iscoupled to the splitter 34 a to permit for the signals to be locked tothe proper and desired frequencies. From the splitter 34 b the firstfrequency is transmitted to a first converter 58 a in order to permitfor the signals or transponders to be converted up to a specifiedfrequency. This up converted signal from the first converter or upconverter 58 a is then transmitted to the satellite receiver by way of aconduit 22 b.

[0044] The second frequencies are transmitted to a first or up converter52 a and then are transmuted to a second or down converter 54 a. Thiswill permit for the signals to be converted to the desired frequency.This second or down converter is coupled to the satellite receiver 21via conduit 22 a. The signals from down converter 54 a and from upconverter 58 a are in the original state, both frequency and polarity,when transmitted from the satellite to the head-in processor 14 a, vialines 26 a and 26 b. The re-converted signals, frequencies and polarityin its original state, is transmitted to the satellite receiver 21 vialines 22 a and 22 b. The satellite receiver 21 is coupled to a source 20(illustrated as a television) to provide for proper transmission of thesignals. The transmission line between the satellite receiver 21 andsource 20 is illustrated but not labeled.

[0045] Hence, it is seen that the head-in processor converted thesignals to different frequency to enable the transmission of twoseparate polarized signals via a single co-axial cable to a head-outprocessor. From the head-out processor, the signals are re-converted totheir original state, which was received via lines 26 a and 26 b. Forexample, with satellite systems, frequencies typically range between950-1450 MHz. If the satellite transmits a frequency of 1450 for boththe horizontal and vertical polarities, then one of the polarities, suchas horizontal, is converted down to 560 MHz via converter 28. The secondfrequency of the second polarity, such as vertical, is first convertedup to 2010 and then back down to 1070, via converters 30 and 36,respectively. Such a conversion allows for the two frequencies of twodifferent polarities, 560 MHz (horizontal) and 1070 MHz (vertical), tobe transmitted simultaneously on a single co-axial cable (16 b).

[0046] As illustrated, this head-out frequency processor is the reverseprocess of the head-in processor. This is to provide for the signals toreconverted to its original frequencies so as to provide for thesatellite receiver 21 and source 20 to accept the signals. The singlecable 16 b accepts the signals at frequencies different than that of thesource. Accordingly, the head-out processor must reconvert the signalsto the frequencies that are utilized by the source 20.

[0047] An alteration of the satellite receiver requires an alteration inthe head-out receiver processor. This alteration is illustrated in FIG.2 and is shown in outline designated as reference 18 b. In this designand configuration, the satellite receiver utilizes only one wire andaccepts only one type of signals, selectively, such as only left-handcircular or only right hand circular polarized signals.

[0048] As seen, the frequencies are tapped via 50 b. The tap 50 b iscoupled to the head-out processor 18 b via line 16 b which is connectedto a four (4) way splitter 34 c. To provide for the signals to be lockedin proper frequencies, the four way splitter is coupled to a phase lockloop (PLL) receiver 56 b.

[0049] From the splitter 34 c, the first signal of a first polarity istransmitted to a first or up converted 52 b and then is transmitted to asecond or down converter 54 b. The conversion of the signals from up todown provides the benefit of converting the frequency without any mishapor error. This method of conversion will avoid the forbidden conversionarea as well as provide for the original received frequency and polarityof the signals.

[0050] The signals of the second frequency and second polarity aretransmitted to an up converter 58 b which will inherently convert thesignals to its original received frequency while maintaining itspolarity. A polarity switch 60 is connected to converters 52 b, 54 b,and 58 b for coupling the head-out processor to the satellite receivervia a single cable 22 c and a joining means, which is a four waysplitter 34 d. The satellite receiver 21 is connected by way of a line(illustrated, but not labeled) to a source 20. In this embodiment, theswitch 60 is used to determine which polarity will enter into thehead-out processor 18 b.

[0051] In the embodiments shown above, the satellite receiver 21 andsource 20 are conventional components and as such, their schematics arenot shown in further detail. The up and down converters used in theembodiment above will be discussed in further detail in FIG. 3a and FIG.3b. FIG. 3a represents the schematic rendering of the down converters(28, 36, 54 a, and 54 b) and FIG. 3b represents the schematic renderingof the up converters (30, 52 a, 52 b, 58 a, and 56 b).

[0052] As seen in the schematic diagram of FIG. 3a, the signal entersthe down converter via line L1. The entered signal passes through afirst capacitor C1 which is coupled to an amplifier AMP. After passingthe amplifier AMP, the signal passes a second capacitor C2 beforeentering a first low pass filter LPF1. This first LPF1 is coupled to amixer which is coupled to a second LPF2. This second LPF2 is connectedto a third capacitor C3 which is coupled to a second choke CH2. Themixer is also connected to an oscillator OSC. The oscillator is coupledto a PLL. The first capacitor C1 is also connect to a first choke CH2.Capacitors C are coupled to the amplifier, oscillator, phase lock lopePPL, and the second low pass filter. Resistors R are coupled to theamplifier, oscillator, first low pass filter and mixer. Chokes are alsocoupled in series with capacitors C to provide for the chokes to beparallel with the amplifier AMP and the second low pass filter,respectively. As seen the chokes CH1 and CH2 (inductors) and capacitorsC are a DC bypass filter network and provide a DC path and enablespassing DC power to the antenna electronics.

[0053] The up converter is disclosed in FIG. 3b. As seen in thisdrawings, the signal enters the up converter via a first line L2. Theconverter further includes an amplifier AMP that is coupled to a firstlow pass filter LP1. The amplifier is also coupled to an oscillator OSC.The oscillator and the first low pass filter are connect to a mixer.This mixer is coupled to a high pass filter HPF. The oscillator is alsoconnected with a phase lock loop receiver PLL. A second amplifier AMP2is coupled to the high pass filter HPF. A second low pass filter LPF2 iscoupled to the second amplifier. Capacitors C are coupled to the firstamplifier, first lower pass filter, and a the amplifier. Resistors R arecoupled other first and second amplifiers, oscillator, first low passfilter, and mixer. Chokes are also used in this circuit. The first chokeis coupled to a capacitor which is coupled to the first amplifier. Thesecond chock is coupled to the phase lock loop.

[0054] Simplifying the system described above, will provide a secondembodiment for the satellite broadcast receiving and distributionsystem. This second system is illustrated in further detail in FIG. 4.This embodiment simplifies the above describe embodiment and alsoprovides a device which avoids the forbidden path. Alteration for thisembodiment occurs in the head-in equipment frequency processor 14 b andthe head-out frequency processor 18 c.

[0055] As with the first embodiment, a low-noise block converter (LNB)24 will receive the signals from the satellite 12. This LNB 24, asstated previously is conventional and is used for amplifying therespective polarized signals (Vertical-polarized signals andHorizontal-polarized signals or left-hand circular and right-handcircular polarization signals). Hence, after signals are received, theypass the low-noise block converter 24, to provide for the signals toenter the head-in equipment frequency processor 14 b (illustrated inFIG. 4 as dashed lines) via conduits 26 a and 26 b, respectively.

[0056] The head-in equipment frequency processor 14 c provides for thesignals to be converted, via converters 28 and 30, as identified for thefirst embodiment. Thereby providing a system which includes frequenciesthat the present day amplifiers can transport. In this stage of thesystem, the object is to convert the signals of one polarity up (viaconverter 30) and to convert the signals of second polarization down(via converter 28).

[0057] From the conduits 26 a and 26 b, the signals are transmitted to afirst converter or down converter 28 and a second converter or upconverter 30. These frequency converters, 28 and 30, respectively,convert the entered frequencies to a frequency which present dayamplifies can transport. The converters have been discussed in furtherdetail in FIGS. 3a and 3 b. The utilization of two converters permit forthe acceptance of two signals or polarized transponders that are of adifferent frequency.

[0058] In the down converting means 28, the transponder is converteddown to a specified frequency. The specified frequency is the frequencythat is required for the present day amplifiers for transportation.Though not illustrated, the newly converted frequencies are amplifiedthrough the amplifying means, as illustrated in FIG. 2 via element 32 a.At the amplifying means 32, the converted frequencies are amplified sonot to create second harmonics. These signals are then transferred to aconventional two way splitter 34 c.

[0059] In the up converting means 30, the transponders are converted upto a specified frequency. The converted signals are transferred to thetwo-way splitter 34 c in order to combine the frequency of the amplifiedsignal and frequency. To synchronized the system, the frequencies fromthe phase lock loop (PLL) transmitter 38 a are transmitted to thesplitter 34 c.

[0060] From the splitter 34 c, the signals are passed through aconventional tilt and gain 62. This will permit for the dual frequenciesfrom the satellite dish 12 to be transmitted simultaneously via a singlecoaxial cable 16 b. Dependent upon the length of the cable, an optionalconventional amplifier 42 can be coupled thereto. Power from a powersource 44 is inserted into the lines via a power inserter 46. Thesignals are amplified, as needed, with additional amplifiers 48. It isnoted that the amplifiers are optional and are dependent to the distancethat the head-in frequency processor 14 b is located from the head-outfrequency processor 18 c. The power supply and power source 11 energizethe head-in frequency processor 14 a.

[0061] From the single coaxial cable 16 b, the signals are adjusted viaa tap 50 a to permit for the appropriate decibels that are required forthe head-out processor 18 a or 18 b.

[0062] The head-out frequency processor used for the head-in processor14 b is illustrated in by way of dash line 18 c. As seen in thisembodiment, the simultaneously transmitted signals enter the processorvia conduit 16 b. The conduit 16 b is coupled to a conventional two (2)way splitter 34 d. A conventional phase lock loop (PLL) receiver 56 a iscoupled to the splitter 34 d to permit for the signals to be locked tothe proper and desired frequencies. From the splitter 34 d the firstfrequency is transmitted to a first converter 52 c in order to permitfor the signals or transponders to be converted up to a specifiedfrequency. This up converted signal from the first converter or upconverter 52 c is then transmitted to the satellite receiver by way of aconduit 22 a.

[0063] The second frequencies are transmitted to a down converter 54 c.This will permit for the signals to be converted to the desiredfrequency. This second or down converter is coupled to the satellitereceiver 21 via conduit 22 b. The signals from down converter 54 c andfrom up converter 52 c are in the original state, both frequency andpolarity, when transmitted from the satellite to the head-in processor14 b, via lines 26 a and 26 b. The reconverted signals, frequencies andpolarity in its original state, is transmitted to the satellite receiver21 via lines 22 a and 22 b. The satellite receiver 21 is coupled to asource 20 (illustrated as a television) to provide for propertransmission of the signals. The transmission line between the satellitereceiver 21 and source 20 is illustrated but not labeled.

[0064] Hence, it is seen that the head-in processor converted thesignals to different frequency to enable the transmission of twoseparate polarized signals via a single co-axial cable to a head-outprocessor. From the head-out processor, the signals are re-converted totheir original state, which was received via lines 26 a and 26 b. Theabove identified embodiment is ideal for long distant use, i.e.exceeding 1000 feet. However, for shorter distance, i.e. less than 1000feet, the components can be simplified again to provide for a devicewhich is ideal for use in apartments or the like.

[0065] As seen in FIG. 5, the present invention includes the head-inequipment frequency processor 14 c and the head-out frequency processor18 d.

[0066] As with the first and second embodiments, a low-noise blockconverter (LNB) 24 will receive the signals from the satellite 12. ThisLNB 24, as stated previously is conventional and is used for amplifyingthe respective polarized signals (Vertical-polarized signals andHorizontal-polarized signals or left-hand circular and right-handcircular polarization signals). Hence, after signals are received, theypass the low-noise block converter 24, to provide for the signals toenter the head-in equipment frequency processor 14 c (illustrated inFIG. 5 as dashed lines) via conduits 26 a and 26 b, respectively.

[0067] As seen, this head-in equipment frequency processor 14 c issimplified. The head-in equipment frequency processor 14 c, provides forsignals of one frequency to be converted, up via converter 30, asidentified for the first embodiment. Thereby providing a system whichincludes frequencies that the present day amplifiers can transport. Inthis stage of the system, the object is to convert the signals of onepolarity up (via converter 36). The signal of the second polarity isamplified via conventional amplifier 32 a.

[0068] From the conduits 26 a and 26 b, the signals are transmitted to afirst converter or down converter 52 d and a amplifier 32 a. The downconverters have been discussed in further detail in FIG. 3a.

[0069] From the amplifier and up converter, the signals are transferredto a conventional hybrid mixer 34 a. From the mixer, the signals pass adiplexer. Exiting the diplexer can occur via a single co-axial cable 16a.

[0070] From the single coaxial cable 16 a, the signals can be adjustedvia a tap (illustrated, but not labeled) to permit for the appropriatedecibels that are required for the head-out processor 18 d.

[0071] The head-out frequency processor used for the head-in processor14 c is illustrated in by way of dash line 18 d. As seen in thisembodiment, the simultaneously transmitted signals enter the processorvia conduit 16 b. The conduit 16 b is coupled to a conventional mixer 36b. to the proper and desired frequencies. From the mixer 36 b the firstfrequency is transmitted to an amplifier 32 b and the second frequencyof a different polarity is transferred to a down converter 52 d forconverting the frequency to its original state.

[0072] The re-converted signals, frequencies and polarity in itsoriginal state, is transmitted to the satellite receiver 21 via lines 22a and 22 b. The satellite receiver 21 is coupled to a source 20(illustrated as a television) to provide for proper transmission of thesignals. The transmission line between the satellite receiver 21 andsource 20 is illustrated but not labeled.

[0073] Hence, it is seen that the head-in processor converted thesignals to different frequency to enable the transmission of twoseparate polarized signals via a single co-axial cable to a head-outprocessor. From the head-out processor, the signals are re-converted totheir original state, which was received via lines 26 a and 26 b. Theabove

[0074] The satellite system of the present invention will permit for twosignals of different frequency and polarities to travel simultaneouslyvia a single coaxial cable. The use of this will provide for a satellitesystem that is versatile, economical and compact. The usage of thesingle cable permits for a system that can accept satellite broadcastingin places that were previously render impossible. These places includemid/high-rise office buildings, condominiums, hospitals, schools, etc.The unique design and configuration enables the signals to betransmitted via the existing wiring of the buildings. The onlyrenovations that may need to be done is the upgrading of the existingamplifiers.

[0075] While the invention has been particularly shown and describedwith reference to an embodiment thereof, it will be understood by thoseskilled in the art that various changes in form and detail may be madewithout departing from the spirit and scope of the invention.
